Quick Answers

So, is Core 2 Extreme X9100 better than Pentium G620T?

Yes. Core 2 Extreme X9100 is the better all-around CPU here. It gives you a 5.3% average FPS lead across 50 shared CPU game tests in our data and 0.4% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core 2 Extreme X9100 is the better pick. According to our tests, it delivers 5.3% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core 2 Extreme X9100 is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core 2 Extreme X9100 is still the much better call for a fresh build. Core 2 Extreme X9100 comes in 1229.7% more expensive on MSRP at $851 MSRP versus $64 MSRP, and it still gives you a 5.3% average FPS lead across 50 shared CPU game tests in our data. Pentium G620T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 1224.5% better value on paper (32.1 vs 2.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

Which one is more future-proof for 2026 and beyond?

Pentium G620T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2008). That makes it the safer long-term bet.
